Cummins ISB CM850 (2003-06) Fault Code: 2266 PID: SID 126 SPN: 1075 FMI: 4 Electric Lift Pump for Engine Fuel Supply Circuit – Voltage Below Normal, or Shorted to Low Source. Low signal voltage detected at the fuel lift pump circuit. This fault code becomes active whenever the ECM detects a short circuit to ground or high current in the electric lift pump circuit. Causes for this fault code are short circuit to ground or low resistance. On 12 VDC Automotive and 24 VDC Industrial or Marine systems during cold weather, gelled fuel can plug the lift pump and cause...
Cummins ISB CM850 (2003-06) Fault Code: 227 (Auto) PID: SID 232 SPN: 1080 FMI: 3 Sensor Supply 2 Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at sensor supply number 2 circuit.

Cummins ISB CM850 (2003-06) Fault Code: 227 (Auto) PID: SID 232 SPN: 1080 FMI: 3 Sensor Supply 2 Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at sensor supply number 2 circuit. High voltage on the +5 VDC supply line can be caused by a signal shorted to battery voltage in the engine harness or connectors, or a failed ECM. On-Board Diagnostics (OBD) Information (Euro 4 Certified Engines): 1)The ECM illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.2)The ECM turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles...

Cummins ISB CM850 (2003-06) Fault Code: 2271 PID: 27 SPN: 27 FMI: 3 Exhaust Gas Recirculation (EGR) Valve Position Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at the EGR valve position sensor circuit. The EGR valve position sensor shares Supply and Return wires in the engine harness with other sensors. Open circuits and short circuits in the engine harness can cause multiple fault codes to be active. Possible causes: 1)Open return in the harness, connectors, or sensor2)SIGNAL wire shorted to sensor supply or battery voltage3)Failed EGR valve position sensor4)Failed ECM. Possible repairs:...
